Osisko Metals Reports Preliminary Metallurgical Testwork Results From Gaspé Copper
The crushed material was blended and split into 24 kg sub-lots, each sub-lot was rotary split into 2 kg charges.
- The crushed material was blended and split into 24 kg sub-lots, each sub-lot was rotary split into 2 kg charges.
- Metallurgical samples comprising drill core were crushed, split and sub-sampled for comminution testwork and head assays.
- Copper was analyzed using atomic adsorption (AA) spectroscopy, and molybdenum and silver by inductively coupled plasma – optical emission spectroscopy (ICP-OES).
- A composite sample was initially tested with average copper grade to determine the optimal grind size for further flotation tests.
